Mushroom shelf (adding third growth stage)

Currently the shelf mushroom have only two stages of growth, i suggest adding a third stage where it gets bigger to reach the top block high and expand on both left and right sides to be able to put candles, flower pots on top of them and put ones next to each other and they feel connected, that would actually make them a block that you find in every player's house and in every builder's inventory, i feel it's a good touch and cozy edition to the Minecraft furniture, since this update brought the wool stairs which now players use as sofa.
